When you hear metformin, an oral biguanide that lowers blood sugar by decreasing liver glucose production and improving insulin sensitivity. Also known as Glucophage, it’s the first‑line drug for many people with type 2 diabetes, a chronic condition where the body can’t use insulin effectively.
Metformin belongs to the biguanides, a class of medications that work mainly on the liver to reduce glucose output. This class also includes older drugs like phenformin, but metformin is the safest and most widely used today. Because it targets the liver, it helps keep fasting glucose levels steadier, which in turn reduces the spikes that can damage blood vessels over time.
One key benefit is its impact on insulin resistance, the reduced ability of cells to respond to insulin. By making cells more responsive, metformin lowers the amount of insulin the pancreas needs to release. This dual action—cutting liver output and boosting cell response—creates a powerful synergy that many patients notice as better energy and fewer sugar cravings.
Beyond blood sugar, metformin shows perks that spill over into other health areas. Some studies link it to modest weight loss, especially when paired with a balanced diet and regular exercise. Others suggest it may improve lipid profiles by lowering LDL cholesterol, which supports heart health—a major concern for anyone with diabetes.
Safety is a frequent question, and it’s worth noting that metformin has a very low risk of causing low blood sugar (hypoglycemia) when used alone. The most common side effects are mild gastrointestinal issues, like nausea or loose stools, which often fade after a few weeks or with a gradual dose increase. For people with kidney problems, doctors may choose an adjusted dose or an alternative medication to avoid rare lactic acidosis.
When you start metformin, the typical starting dose is 500 mg once daily, slowly building up to 1500‑2000 mg split into two doses. This titration helps the stomach adjust and keeps side effects at bay. Taking it with meals also cushions any stomach upset. If you ever miss a dose, just take it as soon as you remember unless it’s almost time for the next one.
